The invention relates to novel fluoromethoximino compounds, to a process for their preparation and to their use as pesticides, and also to novel intermediates and to a plurality of processes for their preparation.

The invention relates to novel fluoromethoximino compounds, to processes for their preparation and to their use as pesticides, and also to novel intermediates and to a plurality of processes for their preparation.

It is already known that certain fluoromethoximino compounds which are constitutionally similar to the compounds described below have fungicidal properties (compare, for example, WO 95/17 376 and DE-9 611 653). However, in many cases, the fungicidal activity of these compounds is unsatisfactory.

This invention, accordingly, provides the novel fluoromethoximino compounds of the general formula (I)

in which

Q¹ represents oxygen or —NH—,

R represents a grouping

in which

Ar represents optionally substituted aryl,

Q² represents oxygen or sulphur,

X represents hydrogen or halogen and

L¹, L², L³ and L⁴ are identical or different and independently of one another each represents hydrogen, halogen, cyano, nitro, in each case optionally halogen-substituted alkyl, alkoxy, alkylthio, alkylsulphinyl or alkylsulphonyl.

Aryl preferably represents aromatic, mono- or polycyclic hydrocarbon rings, such as, in particular, phenyl, naphthyl, anthranyl, phenanthryl, preferably phenyl or naphthyl, especially phenyl.

Halogen preferably represents fluorine, chlorine, bromine or iodine, in particular fluorine, chlorine or bromine.

Furthermore, it has been found that the novel fluoromethoximino compounds of the general formula (I) are obtained when (process a) hydroxyaryl compounds of the general formula (II)

in which

Q¹, L¹, L², L³ and L⁴ are as defined above,

are reacted with a heterocyclyl derivative of the general formulae (III), (IV), (V), (VI), (VII) or (VIII)

in which

Ar, Q² and X are as defined above and

X¹, X², X³, X⁴, X⁵ and X⁶ represent halogen, alkylsulphonyl or arylsulphonyl,

if appropriate in the presence of an acid acceptor and if appropriate in the presence of a diluent.

It is also possible to obtain fluoromethoximino compounds of the formula (I) where the meaning of Q¹ is NH (process a1) by reacting fluoromethoximino compounds of the formula (I) according to the invention where the meaning of Q¹ is oxygen with methylamine, if appropriate in the presence of a diluent, such as, for example, methanol, ethanol or tetrahydrofuran.

Finally, it has been found that the fluoromethoximino compounds of the formula (I) have very good microbicidal properties and can be used for protecting plants against harmful organisms.

Surprisingly, the substances according to the invention have better activity than constitutionally similar active compounds of the prior art with the same direction of action.

If appropriate, the compounds according to the invention can be present as mixtures of different possible isomeric forms, in particular stereoisomers, such as, for example, E and Z. What is claimed are both the E and the Z isomers, and also any mixtures of these isomers.

Depending on their particular physical and/or chemical properties, the active compounds can be converted into the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols and microencapsulations in polymeric substances and in coating compositions for seeds, and ULV cool and warm fogging formulations.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is, liquid solvents, liquefied gases under pressure, and/or solid carriers, optionally with the use of surfactants, that is, emulsifiers and/or dispersants, and/or foam-formers. If the extender used is water, it is also possible to employ for example organic solvents as auxiliary solvents. The following are mainly suitable as liquid solvents: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes oL methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, alcohols such as butanol or glycol and their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide or dimethyl sulphoxide, or else water. Liquefied gaseous extenders or carriers are to be understood as meaning liquids which are gaseous at standard temperature and under atmospheric pressure, for example aerosol propellants such as halogenated hydrocarbons, or else butane, propane, nitrogen and carbon dioxide. Suitable solid carriers are: for example ground natural minerals such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals such as highly disperse silica, alumina and silicates. Suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite, dolomite, or else synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks. Suitable emulsifiers and/or foam-formers are: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates, or else protein hydrolysates. Suitable dispersants are: for example lignin-sulphite waste liquors and methylcellulose.

Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol, polyvinyl acetate, or else natural phospholipids such as cephalins and lecithins and synthetic phospholipids can be used in the formulations. Other additives can be mineral and vegetable oils.

It is possible to use colourants such as inorganic pigments, for example iron oxide, titanium oxide, Prussian Blue and organic dyestuffs such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations generally comprise between 0.1 and 95 per cent by weight of active compound, preferably between 0.5 and 90%.

The active compounds according to the invention can be used as such or in their formulations also mixed with known fungicides, bactericides, acaricides, nematicides or insecticides in order thus, for example, to widen the spectrum of action or to prevent development of resistance. In many cases, synergistic effects are achieved, i.e. the efficacy of the mixture exceeds the efficacy of the individual components.

It is also possible to admix other known active compounds, such as herbicides or fertilizers and growth regulators.

The active compounds can be used as such or in the form of their formulations or the use forms prepared therefrom, such as ready-to-use solutions, suspensions, wettable powders, pastes, soluble powders, dusts and granules. They are used in the customary manner, for example by pouring, spraying, atomizing, spreading, dusting, foaming, brushing on and the like. It is further possible to apply the active compounds by the ultra-low volume method or to inject the active compound formulation, or the active compound itself, into the soil. The seed of the plants can also be treated.

Using the active compounds according to the invention as fungicides, the application rates can be varied within a relatively wide range, depending on the type of application. In the treatment of parts of plants, the active compound application rates are generally between 0.1 and 10,000 g/ha, preferably between 10 and 1000 g/ha. In the treatment of seed, the active compound application rates are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 10 g per kilogram of seed. In the treatment of the soil, the active compound application rates are generally between 0.1 and 10,000 g/ha, preferably between 1 and 5000 g/ha.

The compositions employed for protecting industrial materials generally comprise the active compounds in an amount of from 1 to 95%, preferably from 10 to 75%.

The use concentrations of the active compounds according to the invention depend on the species and the occurrence of the microorganisms to be controlled and on the composition of the material to be protected. The optimum rate of application can be determined by test series. In general, the use concentrations are in the range from 0.001 to 5% by weight, preferably from 0.05 to 1.0% by weight, based on the material to be protected.

The efficacy and the activity spectrum of the active compounds to be used according to the invention in the protection of materials, and/or of the compositions, concentrates or quite generally-formulations preparable therefrom can be increased by adding, if appropriate, further antimicrobially active compounds, fungicides, bactericides, herbicides, insecticides or other active compounds for broadening the activity spectrum or to obtain particular effects, such as, for example, additional protection against insects. These mixtures may have a broader activity spectrum than the compounds according to the invention.

PREPARATION EXAMPLES Example 1

Process a)

A mixture of 0.6 g (0.003 mol) of methyl 2-fluoromethoxyimino-2-(2-hydroxy-phenyl)-acetate, 0.6 g (0.003 mol) of 4-(2-chlorophenoxy-5,6-difluoropyrimidine and 0.4 g of potassium carbonate in 20 ml of acetonitrile is stirred at 50° C. overnight. After cooling, the mixture is concentrated under reduced pressure, and the residue is taken up in ethyl acetate, washed with water, dried over sodium sulphate and once more concentrated under reduced pressure. The residue is chromatographed over silica gel using hexane/acetone (4:1). This gives 0.3 g (22% of theory) of methyl {2-[6-(2-chlorophenoxy)-5-fluoropyrimidin-4-yloxy]-phenyl}-fluoromethoxyimino-acetate of melting point 153-155° C.

Example 2

Process a)

A mixture of 25 g (0.111 mol) of 2-fluoromethoxyimino-2-(2-hydroxyphenyl)-N-methylacetamide, 26.8 g (0.111 mol) of 4-(2-chlorophenoxy-5,6-difluoropyrimidine and 18.3 g of potassium carbonate in 300 ml of acetonitrile is stirred at 50° C. overnight. After cooling, the mixture is poured into ice water and extracted twice with dichloromethane. The combined organic phases are dried over sodium sulphate and concentrated under reduced pressure. The residue is chromatographed over silica gel using hexane/acetone (7:3). This gives 27.3 g (55% of theory) of 2-{2-[6-(2-chlorophenoxy)-5-fluoropyrimidin-4-yloxy]-phenyl}-2-fluoromethoxyimino-N-methylacetamide of melting point 128-129° C.

Example 3

Process a)

0.1 g of an 80% strength suspension of sodium hydride is added to a solution of 0.7 g of 2-fluoromethoxyimino-2-(2-hydroxyphenyl)-N-methylacetamide and 5-phenyl-sulphonyl-3-phenyl-<1,2,4>thiadiazole in 20 ml of N-methylpyrrolidone, and the mixture is stirred at room temperature overnight. The reaction mixture is then concentrated under reduced pressure, and the residue is taken up in ethyl acetate, washed twice with water, dried over sodium sulphate and once more concentrated under reduced pressure. The residue is chromatographed over silica gel using hexane/acetone (4:1). This gives 0.6 g (50% of theory) of 2-fluoromethoxyimino-N-methyl-2-[2-(3-phenyl-[1,2,4]thiadiazol-5-yloxy)-phenyl]-acetamide. logP value: 2.9

Process b)

A solution of 3.1 g (0.01 mol) of methyl 2-fluoromethoxyimino-2-[2-(tetrahydropyran-2-yloxy)-phenyl]-acetate in 30 ml of ethyl acetate is treated with 0.2 g of acidic ion exchange resin and stirred at 20° C. overnight (approximately 16 hours). The ion exchange resin is then filtered off and the filtrate is concentrated under reduced presssure. The residue is chromatographed over silica gel using hexane/acetone (9:1). This gives 0.7 g (31% of theory) of methyl 2-fluoromethoxyimino-2-(2-hydroxy-phenyl)-acetate. logP value: 1.6

Example (II-2)

Process b1)

A solution of 3.1 g (0.01 mol) of 2-fluoromethoxyimino-N-methyl-2-[2-(tetrahydropyran-2-yloxy)-phenyl]-acetamide in 30 ml of methanol is treated with 0.1 g of acidic ion exchange resin and stirred at 20° C. overnight (approximately 16 hours). The ion exchange resin is then filtered off and the filtrate is concentrated under reduced pressure. The residue is chromatographed over silica gel using hexane/acetone (9:1). This gives 0.9 g (40% of theory) of 2-fluoromethoxyimino-2-(2-hydroxyphenyl)-N-methylacetamide. logP value: 1.1

Preparation of Intermediates of the Formula (IX)

Example (VI-1)

Process c)

Over a period of 30 minutes, a solution of 75 g (0.3 mol) of methyl [2-(tetrahydropyran-2-yloxy)-phenyl]-acetate and 102.9 g (0.9 mol) of 90% strength t-butyl nitrite is added dropwise to a solution of 39.6 g (0.33 mol) of potassium tert-butoxide in 360 ml of t-butanol, the temperature of the reaction mixture rising to 45° C. The mixture is stirred at room temperature for 2 hours and then cooled to 15° C., and 51 g (0.45 mol) of bromofluoromethane are added dropwise over a period of from 5 to 10 minutes. The mixture is stirred overnight without any further cooling and then taken up in methyl t-butyl ether, washed with water, dried over sodium sulphate and concentrated under reduced pressure. The residue is chromatographed over silica gel using hexane/acetone (9:1). This gives 42.8 g (4.9% of theory) of methyl 2-fluoromethoxyimino-2-[2-(tetrahydropyran-2-yloxy)-phenyl]-aceta as an oil. logP value: 2.8

Example (VI-2)

Process c1)

With cooling, methylamine is introduced over a period of 15 minutes into a solution of 6.2 g (0.02 mol) of methyl 2-fluoromethoxyimino-2-[2-(tetrahydropyran-2-yloxy)phenyl]-acetate in 50 ml of methanol. The temperature of the solution should not exceed 40° C. Stirring is continued overnight, and the mixture is then concentrated under reduced pressure. The residue is chromatographed over silica gel using hexane/acetone (7:3). This gives 5.5 g (88.7% of theory) of 2-fluoromethoxyimino-N-methyl-2-[2-(tetrahydropyran-2-yloxy)-phenyl]-acetaimide of melting point 81° C.

Preparation of Starting Materials of the Formula (III)

Example (III-1)

At 0° C., a solution of 42.4 g (0.45 mol) of phenol and 50.4 g (0.45 mol) of potassium tert-butoxide in 400 1 of tetrahydrofuran is added dropwise to a solution of 80 g (0.6 mol) of 4,5,6-trifluoropyrimidine 1 l of tetrahydrofuran. After the addition has ended, the reaction mixture is stirred at 0° C. for 30 minutes and then poured into water and extracted with ethyl acetate. The organic phase is dried over sodium sulphate, concentrated under reduced pressure, and the residue is stirred with low-boiling petroleum ether. This gives 63.8 g (68.1% of theory) of 4-phenoxy-5,6-difluoropyrimidine of melting point 65 to 66° C.

Preparation of the Precursor

To dry a mixture of 609 g of potassium fluoride in 2.3 1 of sulpholane, 500 ml of liquid are distilled off at 145° C. and 20 mbar. 1054 g of 5-chloro-4,6-difluoro-pyrimidine (DE-A 384358) and 25 g of tetraphenylphosphonium bromide are subsequently added, 5 bar of nitrogen are applied and the mixture is stirred at 240° C. for 24 hours, the pressure increasing to 11 bar. The reaction mixture is cooled to 80° C. and vented. The mixture is then slowly heated again at atmospheric pressure, and the product is distilled off. Once the bottom temperature has reached 200° C., the pressure is lowered to 150 mbar to accelerate the distillation and to obtain more product. Altogether, 664 g (70.7% of theory) of 4,5,6-trifluoropyrimidine of boiling point 86 to 87° C. are obtained.

The logp values are determined in accordance with EEC Directive 79/831 Annex V. A8 by HPLC (gradient method, acetonitrile/0.1% aqueous phosphoric acid).

The compounds of the formula (I-a) according to the invention listed in Table 1 below are likewise obtained by the methods of Examples (1) to (3), and in accordance with the general description of the preparation processes a) and a1) according to the invention:

USE EXAMPLES Example A

Plasmopara Test (Grapevine)/Protective

Solvent: 47 parts by weight of acetone

Emulsifier: 3 parts by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amounts of solvent and emulsifier, and the concentrate is diluted with water to the desired concentration.

To test for protective activity, young plants are sprayed with the preparation of active compound at the stated application rate. After the spray coating has dried on, the plants are inoculated with an aqueous spore suspension of Plasmopara viticola and then remain in an incubation cabin at approximately 20° C. and 100% relative atmospheric humidity for 1 day. The plants are subsequently placed in a greenhouse at approximately 21° C. and approximately 90% relative atmospheric humidity for 5 days.
